7. Quit this: Hawaiian shirtsHawaiian shirts are appropriate on only one occasion, and that is on Charlie Sheen. Any other time is just an insult to Charlie Sheen…which is kind of all right.

Hit this: Paisley shirtsOdds are you won’t need much to cheer you up this 420, but paisley, like this Michael Kors top, can add a dash of curlicued sunshine to anyone’s day.

8. Quit this: Baggy jeans
“So okay, I don’t want to be a traitor to my generation and all but I don’t get how guys dress today. I mean, come on, it looks like they just fell out of bed and put on some baggy pants and take their greasy hair – ew – and cover it up with a backwards cap and like, we’re expected to swoon? I don’t think so.” – Cher Horowitz

Hit this: Harem pantsA harem pant gives you the same freeballin’ feeling of a pair of slouchy Levi’s hanging off your upper thighs and — bonus points — the drop-crotch acts as a great weed table if nothing else is around.

9. Quit this: American EagleFor most of us, middle school is over and so is the Eagle.

Hit this: American ApparelGoing from the Eagle to the Apparel, though, is not so much a show of growth so much as a show of wanting to get laid. But even stoners need to slut it up sometimes.

10. Quit this: BeaniesA beanie is like the stoner equivalent of the little black dress. And though I would deign to ask any pothead worth his or her reefer to abandon their LBD…

Hit this: NewsboysA newsboy cap adds a certain air of jauntiness and charm. I mean, who would you rather get high with, beanie boy or Brad Pitt? Though the beanie guy looks baked as all get out.
